Motor Application
Brushless (motors) require a drive circuit (driver), which detects the position of the rotor's magnetic poles and transmits an appropriate electric circuit in the windings to rotate.
Brushless motors do not require brushes and rectifiers because the windings do not rotate. Depending on the method of mounting permanent magnets on the rotor, they can be categorized as follows.
1.Surface magnet type (SPM: Surface Permanent Magnet)
2.A permanent magnet is attached to the periphery of the rotor.
3.Built-in magnet type (IPM: Interior Permanent Magnet)
4.A permanent magnet is embedded in the inside of the rotor.
Features of Brushless Motors
1. Longer life because brushes are not used.
2. High-efficiency design.
3. Stable speed control.
4. High-speed rotary operation.
5. High starting torque.
Working Principle of Brushless DC Motor
Lorentz force law which states that whenever a current carrying conductor placed in a magnetic field it experiences a
force. As a consequence of reaction force, the magnet will experience an equal and opposite force. In the BLDC motor, the current carrvina conductor is stationarv and the permanent maanet is movina.
When the stator coils get a supply from source, it becomes electromagnet and starts producing the uniform field in the air gap. Though the source of supply is DC. switching makes to generate an AC voltage waveform with trapezoidal shape. Due to the force of interaction between electromagnet stator and permanent magnet rotor, the rotor continues to rotate.
With the switching of windings as High and Low signals, corresponding winding energized as North and South poles. The permanent magnet rotor with North and South poles align with stator poles which causes the motor to rotate.
Currently, hair dryers use more brushless motors because of the fast speed and low noise, which can maximize the performance of the hair dryer. The recently popular high-speed hair dryer used a significant wind speed drying instead of hot air drying, which protects the hair from injury. The inside of the neutralization ions can be perfect for softening the hair, blowing the hair will not be fried after the blowing, and hair will not be knotted for all kinds of hairstyles and hair textures.
